Something ElseSomething Else's answer:
What makes Else unique is that it lets you prototype and test directly inside your real product codebase rather than on a static mockup or a copy. Because it runs inside your live product with your real data, components, and edge cases, what you test is exactly what your users will see. When the prototype works, Else hands engineering a review-ready PR plus a full backend spec for any new functionality, so engineers don't rebuild from scratch, they review, test, and merge. The result is dramatically faster time to production with PRs that often merge with zero changes.
Something Else's answer:
Unlike tools that generate throwaway mockups or standalone apps, Else works on your actual product, so prototypes don't need to be rebuilt before they can ship. It learns from your codebase to inherit your design system and reuse existing components, then produces a PR engineers can review, test, and merge, often with zero changes. It extends your backend without modifying it and exports a full spec plus an integration prompt for new functionality. For product managers, that means going from validated prototype to production PR up to 90% faster, while keeping the product free of bloat from unused features.
Something Else's answer:
Else's primary audience is product managers who have validated an idea or built a design but watch it stall in the backlog waiting on engineering. It's aimed at PMs who want to prototype and test real features on their actual product and hand engineering a merge-ready PR, without needing to know how to code. It works much like a vibe coding environment, so some technical understanding helps but isn't required. It's a strong fit for teams shipping client-rendered SPA frontends (React, Angular, Vue, etc.) who want to ship small improvements that are too small for a sprint but too big for a hotfix.
Something Else's answer:
Else was created to fix a familiar problem: teams design and validate a change, sometimes even build a Figma prototype everyone loves, and then it lands in the backlog, where it can sit for weeks or months while the customer conversation fades and the details get lost in translation. The core insight is that static mockups lie because they lack your real data, components, and edge cases. So Else was built to let teams prototype on the real product and hand engineering a review-ready PR instead of a brief, turning "review, test, merge" into the only remaining step. Else is backed by a16z Speedrun.

We need to determine the look and functionality of each view in the app. One of the best approaches is to draw each view of the app either using a mockup tool or on paper, this will give you a good idea of what information and data you're planning to have on each page. - Source: dev.to / over 1 year ago

A mockup takes a wireframe to the next level. Depending on how confident you are in the design youโre proposing, you can create a basic mockup or put it more details, like images, colors and even some functionality. You can use tools like Mockflow and Moqups. Source: over 5 years ago
